LORNE A. GRIFFIN AND LOUIS C. VANDEBLIP, OF ELKHART, INDIANA, ASSIGNOBS, BY DIRECT AND MESNE ASSIGNMENTS, T0 AMERICAN STEAM CONVEYOR CORPORATION, OF CHICAGO, ILLINOIS, A CORPORATION OF YORK.

SUCTION'APPARATUS FOB CONVEYER-COND'UITS.

Application filed January 7, 1915, Serial No. 924.

To all whom it may concern:

Be it known that we, LORNE A. GRIFFIN and LOUIS C. VANDERLIP, citizens of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented new and useful Improvements in Suction Apparatus for Conveyor- Conduits, of which the following is a specification.

Our invention relates to suction apparatus for the conveyance of loose, abrasive and relatively disintegrated material in conveyer operation, second, the use of wear liners to protect the interior of the three-way fitting from the abrasive. action of the conveyer contents, and, third, the production of a fitting of the kind described in which the wear lining may be replaced without the removal of the fitting itself from the conduit line.

. In the annexed drawings, Figure 1 is a longitudinal section showing the lining and the gates in position, with one gate open and one closed; Fig. 2 is a section on the line 22 of Fig. 1 with one gate removed; Fig. 3 is an end elevation of a half wearliner;

Fig. a is a side elevation of a half wear liner; Fig. 5 is a section in elevation of a half wea liner; and Fig. 6 is a plan view of the bottom plate; and Fig. 7 is a side view in elevation of the gate valve Gr.

.The component parts of our invention are clearly shown on the annexed drawings,

wherein A is the three-way fitting body, 'B the: bottom plate, C is; a nozzle'for fluid under pressure, 1) isa handhole cover, E and F are half wear liners, G is a gate valve, H 1s a gate valve half body, K is an open gate, and L is a half body for the gate valve.

It frequently occurs that it is necessary tohave two conduit suction lines converge a I common point to expel their contents through a,single discharge conduit Specification of Letters Patent.

line, and in such a case the suction apparatus, or machine, is placed at the point of convergence for the purpose of draw ing the conduit contents from either line thereto and for discharge into the single discharge line. Under such conditions, it becomes necessary, in order to gain the highest efiiciency, to close the conduit line not in use to produce an eflective suction, or vacuum, in the conduit line open to the suction apparatus. Our invention is made in contemplation of such a condition, and by its use two converging suction conduit lines may be alternately used with efficiency.

On the drawings, A is the body of the three-way fitting, or suction machine body, which is provided with the lateral suction inlet openings 1 and 2, and the discharge opening 3. The body portion opposite the discharge opening 8 is provided with a wear lining insertion opening 4: of oval shape adapted to be covered and sealed by the cover plate B of oval formation. The cover plate B is penetrated at or adjacent its cen ter by an opening 5 adapted to receive the fluid nozzle C which may be secured therein in any suitable manner. The issuing end 6 of the nozzle C is substantially coaxial with the discharge opening 3. The annular handhole 8 is formed in one side of the suction machine body A and is adapted to be closed and sealed by the hand hole plate D, the in ner face '9 of which is flat and flush with the adjacent interior surface of the wear liners V E and F.

The wear liners E and F are provided to form one complete removable lining for the suction machine. and are right and left hand in formation. Each liner is provided with annular opening 10 adapted to register with the suction inlet opening 1 or 2. I Each half liner is also provided with a semi-annular lateral opening 11 to form an annular handhole cover opening within which the portion 9 of the handhole cover-D is arranged. The liners E and F extend from the. inner sur face of the bottom plate B to and flush with the face of the discharge opening flange 12 with their edges converging at 13. The discharge opening 14 of the body A is enlarged .to accommodate the liners E and F,

the bore of which at the discharge opening 3 must be substantially equal to the bore of the discharge conduit line andannular in formation. The upper exterior surface of the liners E and F- isoutwardly flaring in 10111121111011 to accommodate the enlargement of the bore of the bend at 16 at the wear surface thereof. And the interior surface 14: of the body A is constructed to conform to the configuration of the surface 15.

At suction inlet openings 1 and 2 are provided the gate valve slots 17 formed by the combination of the flanges 18 and 18, integral.

with body A, and the detachable flanges H and L bolted to flanges 18, and open at 23 and 21, respectively. The slots 17 thus formed taper fromthe top thereof, 19 and 19, the widest part, to the bottom portion 20 and 20, the narrowest portion'thereof, and their inner surfaces are preferably machined to a smooth finish and uniform taper, or

wedge formation.

1 For slidable operation in gate slots 17 the gate valves G and K are provided, each being adapted for slidable operation in both slots 17, and each of wedge formation to fit the slots 17 closely. A handle 21 is provided to manipulate eachvalve G and K. When the suction machine is in use and inlet "opening 2 is open, the solid gate valve is other appropriate manner.

arranged in the slot 17 at opening 1, and the gate K provided with the inlet aperture 22, is arranged in theslot17 of the inlet opening 2 to permit the passage of the mate rial through aperture 22 therein. When material is to be drawn through opening 1, the gates G and K are interchanged, thereby clearing the inlet 1 and closing opening 2.

The gate flanges H and L are adapted to -receivethe, flanges of suction pipe lines to whichthey maybe bolted, or secured in any Bottom plate 13 is secured to member vA by the bolts and nuts 25, and the handhole cover D .to the same member by bolts and nuts 26.
